Hi Tal,

     Thanks for the quick reply.  The answers to your questions:

>do you need bidirectional link or only one direction ?
Only one direction
>Does the baud rate of the RS232 output from the receiving side >must to be
4800 ?
Yes
>What is the max/recommended bit rate for your radio link ?
>Does your radio link has any minimum requirements for bit rate >or can you
send long ones and zero's ?
The modules that I am trying to use are an AMRT4 transmitter, & AMHRR3
receiver, both from www.okwelectronics.com.  I have looked at the data
sheets for both & cannot find any mention of max/recommended bit rate, so I
do not know the answer to this question.
>What is the interface of your radio link (digital, analog, etc).
The interface to both the transmitter & receiver are thru MAX232 chips to
convert the rs-232 to TTL levels.

Thanks again,
David
